Hugely usefulPuntuado con 4 de 5 estrellas

I can't tell you how many times I as a web developer have used this to debug a problem. Far and away more useful than those multitudes of extensions which only monitor headers. The one drawback -- and it's not a small one -- is that it relies on the cache to display some information, so that information isn't available for uncached responses.

Great until it broke recently in FF29 because objects and pages which are not cached are showing up as cached, therefore I am unable to see Response Headers when I need to. Hope the author fixes this. Use Fiddler or Firebug in the interim (requires more clicks/steps to get to the things you want to see, though). He also has yet to fix the icon problem making it harder for some people to find/open HttpFox (use CTRL+Shift+F2 on PC to toggle)

Great but same cache problemsPuntuado con 5 de 5 estrellas

I use this extensions for many years and it is really my preferred tool for debugging web flows.Unfortunately I encounter the same problem as dynahog, some request are marked as "cached" and I know its false. I cannot see the response details. I use FF29. Thank you for your help
